Linear Constant Current LED Driver, Fixed 100mA
SM6801A
GENERAL DESCRIPTION
The SM6801A is designed for driving LEDs at 100mA.
Using linear mode control to regulate LEDs output
current, It is able to operate at very wide supply voltage
from 5.5V to 45V and withstand transients without the
need for additional transient protection circuitry, thus
very suitable for single or multiple series LEDs
applications. The maximum dropout voltage of 1.5V
accommodates extra LEDs, permits lower supply voltage
and provides more efficient operation. Besides, The
SM6801A also built-in over temperature protection shuts
off the LED current when the chip junction temperature
rises above 135℃ (typical). Full LED current resumes
when the chip junction temperature falls below 75℃.
The SM6801A is offered in both T0-252(D-PAK) and
SOT-223 packages. Allowing heat sinking directly to a
chassis without the need for electrically insulating
spacers.
